Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8688844, here are decompositions:

53 + 8688791 = 8688844
137 + 8688707 = 8688844
173 + 8688671 = 8688844
233 + 8688611 = 8688844
251 + 8688593 = 8688844
293 + 8688551 = 8688844
317 + 8688527 = 8688844
347 + 8688497 = 8688844

Showing the first eight; more decompositions exist.
